Lots of people using the t3 8inch with the Pro. Not sure what the difference would be between that and the 9.7 processor wise. You have to use an older version of the Go4 software though....Lag and errors have been reported with the newer versions of the software.
I can confirm that the mediapad t3 9.6, works perfectly on mavic pro with djigo 4 latest version.
Only the usual Android problem that consumes the RC battery, because it feeds the tablet.
